Close Encounters of the Weak Kind: Investigations of Electron-Electron Interactions between Dissimilar Spins in Hybrid Rotaxanes.

ABSTRACT: We report a family of hybrid [2]rotaxanes based on inorganic [Cr₇NiF₈(O₂C^tBu)₁₆]^- ("{Cr₇Ni}") rings templated about organic threads that are terminated at one end with pyridyl groups. These rotaxanes can be coordinated to [Cu(hfac)₂] (where Hhfac = 1,1,1,5,5,5-hexafluoroacetylacetone), to give 1:1 or 1:2 Cu:{Cr₇Ni} adducts: {[Cu(hfac)₂](py-CH₂NH₂CH₂CH₂Ph)[Cr₇NiF₈(O₂C^tBu)₁₆]}, {[Cu(hfac)₂][py-CH₂NH₂CH₂CH₃][Cr₇NiF₈(O₂C^tBu)₁₆]}, {[Cu(hfac)₂]([py-CH
